Patterned implant and method

摘要

A unitary or homogeneous patterned implant is provided. The implant is constructed of patterned cells formed by way of a molding, die casting, laser etching, laser cutting, extruding, and the like. Portions of the implant can be formed into sinusoid or other waveform strut members to control and promote elongation, expansion or contraction along single or multiple axes. As such, controlled and designated stress, tension and compression distribution is promoted across specific or localized areas of the implant.

主权项

1. A unitary patterned implant device for treating vaginal prolapse in a patient, comprising:
a non-woven unitary support portion including a plurality of undulating strut members joined at and spanning out from a plurality of fixed junctions to define a plurality of substantially identical repeating cells having voids, the support portion having first and second opposing eyelets; first and second opposing anchor portions provided a distance from the first and second opposing eyelets, with each of the first and second opposing anchor portions further including a cylindrical rod extending out from the anchor portions and a tissue anchor provided at a distal end of the cylindrical rod of each of the first and second opposing anchor portions, the tissue anchor having one or more angled tines and an anchor length; at least one transition zone integrally formed with the support portion and the first anchor portion, defining a plurality of generally elongate non-woven cells of a different shape and larger than the substantially identical repeating cells of the support portion, and spanning between the support portion and the first anchor portion such that the at least one transition zone tapers and narrows from the support portion to the first anchor portion; and an anchoring arm having a distal tissue anchor and an extending rod member adapted to slidably engage and secure with one of the first and second eyelets of the support portion.
